Writing Suspense

I like reading books that have some suspense, so I also like to write books with suspense. I like to have suspense at the end of a chapter, so the reader find himself/herself wanting to keep reading to find out what happens next. That is one way I keep my readers' attention from the beginning of the book to the end. Another way I create suspense is moving from one scene to another at a very suspenseful part of each scene. I use "~  ~  ~" to let the read know I am switching scenes. It's enjoyable for me to re-read my books, so hopefully my readers agree.
